EU 33 reaches US 13, the last number before the US children's scale restarts at 1 for bigger feet, so 13 here is a large child's size, not an adult one.
Brand fit: East European shoes stamp the metric length inside, so this 200 mm foot reads as a plain 200 there, and GOST's 5 mm grid matches this row step for step.
US to EU conversion
The kids' US to EU gap starts near 16 and holds until the US scale resets: at a 210 mm foot US jumps back to 1, so the gap leaps to 33 and EU 34 sits opposite US 1. Below the reset US 9 is EU 26; above it US 2 is EU 35.5, the same digit meaning two very different feet. That break is why an online chart that assumes one fixed offset misfires exactly where a child crosses from little-kid to big-kid sizes.
At this size, US to EU
One size up from US 13, EU moves 0.5 to EU 33.5 while US rises 0.5 to US 13.5, holding their spacing. Both US 13 and EU 33 are whole numbers here, so nothing rounds. For US 13, the EU column here runs EU 32, EU 33, EU 33.5, stepping a half size at a time.

Frequently Asked Questions Does US 13 round up or down in EU? Round up for growth, but do not read the coming US 1 as smaller: it sits one length above US 13, and foot length, not the number, tells you which is bigger.
